The vaccine utilizes graphene oxide as a carrier for the coronavirus protein. The vaccine is a recombinant protein vaccine developed for COVID-19. The vaccine contains a combination of proteins including N-beta-alanyl-L-histidine and carnosic acid. The vaccine is prepared using a chemical reaction and ultra-filtration method. The vaccine is tested using a CpG oligodeoxynucleotide
mRNA-based vaccine developed by BioNTech and Pfizer for COVID-19 protection. Contains nucleoside-modified mRNA encoding SARS-CoV-2 spike protein. Initial two-dose regimen recommended, later extended to 42 days. First vaccine authorized for emergency use in UK in December 2020
mRNA vaccines use messenger RNA to stimulate immune response against pathogens. mRNA is delivered through lipid nanoparticles to protect and enter cells. Vaccines can induce both cellular and humoral immunity
